//
// NonDeserializableObject is, in general, deserializable, but on a Geode server
// it can't be deserialized because it has no default ctor, and thus can't be
// instantiated via reflection.  This is interesting because it's possible to,
// for instance, execute a function server-side which returns an instance of
// this class, which causes Geode to return a payload of type 'DataSerializable'
// with subtype 'Class', and the class name and data necessary to recreate the
// object in a client whieh supports reflection.  Since C++ doesn't have this,
// the Geode Native Client should throw an exception, and that's what we use
// this class to test.
